compiling mirah

[Michal Hantl]

Hey guys,
yesterday I was forced to reinstall ubuntu and I am having hard time
running my project again.

Mirah 0.0.7 complained about invalid method name "[]" and I relized I
was using 0.0.8 so I went to grab the sources and compile the thing.

First, Bitescript compiled and installed as a gem, good.
The I went to compile mirah and got this:

michal@michal-P5Q-PRO:~/dev/mirah$ rake gem --trace
(in /home/michal/dev/mirah)

Is it possible that I should not use openjdk?
Did this happen to you?

Thanks.

I think this is because latest bitescript requires jruby head to work. I checked out the bitescript commit before headius added invokedynamic support, and that seemed to work.

[Michal Hantl]

Ahh, I only tried:

To build and install from source,

$ git clone http://github.com/headius/bitescript.git
$ git clone http://github.com/mirah/mirah.git
$ cd bitescript
$ gem build bitescript.gemspec
$ gem install bitescript-*
$ cd -
$ cd mirah
$ rake gem
$ gem install pkg/mirah-*
$ cd -

and that didn't work, but this is important:

this is also what the readme says:

== For Java tools:

To build the Mirah jars from source you should have a checkout of both jruby and
bitescript in Mirah's parent directory. Run "ant jar-complete" in jruby, then in
the mirah directory "../jruby/bin/jruby -S rake jar" to build the Mirah jar. Use
"jar:complete" instead to produce a free-standing jar file with JRuby and the
JRubyParser libraries included.

Thanks!

So I am running on latest jruby, mirah and bitescript, but I still get
this exception:

This goes for every controller I have. It used to compile before i
reinstalled ubuntu.. I'll try to run this with sun java tomorrow.

Do you have a method named []? If so, it needs to be a macro.

[Michal Hantl]

Hmm, so th mirah 008 I used is a bit different than the one I compiled
now. That makes sense!

so how do I convert this method to a macro?

def [](param:String); returns String
@request.getParameter(param)
end

[Nick Howard]

macro def [] param

  quote do

    getRequestParam `param`

  end

end

def getRequestParam param:String; returns String

  @request.getParameter param

end

would work I think.

I just needed the same [] macro again and I noticed I hadn't thank you yet.

So.. thank you! :)
